PCV help needed

Hi guys,
I am having a problem with my 134F (totally stock 1957 CJ5) engine pumping out oil (seams to be either from the oil fill port or the oil filter..... I am not really sure where the oil is coming from). I can run the engine at 2000 rpms for 30 minutes and I get nothing, but if I drive it down the road a mile, everything gets covered with oil. My best guess is that the PCV is not connected properly but I have it connected the way I got it. here is a pic of the PCV (I know it is supposed to run to the carb area..... but like I said, this is the way I got it ):

Does this look like it should work? What else could be the problem?

thanks,
mike

 

OK, I have an update. I zeroed in on the oil filter. I replaced the filter and the gasket ring and it seams to be holding for now. I will have to keep checking it to make sure the gasket does not fail again.

 

You really do need to re-assemble the PCV system. http://oldjeepcarbs.freeforums.net/board/36/pcv-systems

 

You do know that there are two PCV valves in that picture, right?

 

huh? I only see one.

 

Scoutpilot.... is it OK to just hook the PCV up to the intake manifold vacuum port or do I have to 'T' it off and connect it to the fuel pump vacuum port too? (the literature just says the fuel pump connection is for 'extra' vacuum)

 

Take a look at that picture. You see the round disk there? That is one of the first PCV valves. Should be rotated 90 degrees toward the front, and the steel vacuum line run from it to the port directly under the carb. The rest of that stuff hooked up there is a later model PCV valve. Mounts to a valve cover.

Revision here: By going to the G503 Military Vehicle board and looking at all their pictures I see that actually that whole thing from the round disc to the far end of the tube-like beastie with the arrow on the side is the PCV valve.

I do know that some of them have that side cover reversed and the disc is at the rear instead of the front. This was done for engines that had the governers mounted on the drivers side front of the engine. Jeeps that came with things like the humongous radios the military put in them or big welders or even aircompressors and needed the governer to operate properly. Civilian Jeeps that came with compressors or welders or ditchdigging systems also had them. My '60 has the rear one with a long tube running up to just behind the fuel pump where there is a T that would go to the vacuum pump end of the fuel pump and on to the vacuum operated windshield wipers. the third leg of the T went up and across the front of the engine under the valve cover and then to the port under the carb. If you don't have the vacuum chamber on your fuel pump the windshield wipers will not work right.

 

The motor was designed to operate at peak efficiency with the PCV system connected. Failure to re-connect the PCV system will result in excessive crankcase pressure, which leads to seal/gasket failure, which leads to oil leaks. Also, the moisture and the dirt that build up after the motor is shut off and volatile gases which enter the crankcase from the piston cylinders are not removed and voila, you have sludge sooner than you would normally. Basically, the motor will run, but without the PCV, it won’t run as well and it won’t stay in running condition as long as a motor with it connected.
PS. There is only one PCV valve in the photo.

 

OK, we are in agreement... one PCV in the picture. (I double checked and the round cap is just that... an empty cap that rotates).
Yes, I have the vacuum port on my fuel pump (currently capped off)
I do not have the vacuum operated windshield wipers anymore, so I do not need to connect that up.
So, I guess I need to find a 'T' and some hose fittings so that I can connect the PCV to the fuel pump and intake manifold under the carb
thanks for your help guys,
mike

 

Mmm. Don't think you need to connect to the vacuum pump just for PCV operation (probably couldn't hurt). Mine runs just fine with that T capped off and just connected under the carb. I use the capped T for hooking up my vacuum guage during tune-ups. Easy to reach there and you don't have to unscrew the fittings, just pull the cap.
